Patent CA-2092636-A1 (CA)
Inventor: PERSON HERMAN R
IPC: H01C3/00
Filed: 1993-03-12
Abstract: A bulk metal chip resistor includes an elongated resistor element having terminals at its opposite ends.  The terminals are formed by coating the opposite ends of the resistor element with a conductive material.  Insulative material may be molded around the center portion of the resistor to provide structural support, and the ends of the resistor can be bent downwardly so as to cause the central portion to be raised when the resistor is mounted on a circuit board.  A modified form of the invention includes wrapping the resistance element around the ends of a rectangular substrate so that the substrate provides structural support.  Another modified form includes placing four terminals at the four corners of the resistor element.

Patent CA-2094025-A1 (CA)
Inventor: SEPAVICH DAVID
IPC: B65H19/22
Filed: 1991-09-30
Abstract: An apparatus and method for cross-cutting a traveling web (W) of material, such as paper, while winding the traveling web into successive rolls of a specified diameter includes a laser (48), a pair of spaced adhesive applicators (40, 40') and energy means (44) for activating the adhesive (46) to change it from an essentially inert to a web adhesive state. A pair of horizontally arrayed drums (12, 14) support a core (26) on which the traveling web (W) is wound. Upstream of the core (26), over the lower periphery of one of the drums (12, 14), the on-coming web has its drum-supported surface exposed to a transversely moveable laser (48) which cuts the web transversely to its direction of travel. Upstream of the transversely actuated laser (48) are a pair of adhesive applicator nozzles (40, 40') which are spaced in the web travelling direction and movable transversely with the laser (48). An ener-gy means (44) is mounted between the adhesive nozzles (40, 40') and laser (48) to activate the adhesive sprayed by the nozzles. The travelling web can, thus, be severed by the laser (48) and have its trailing edge glued to the web roll being wound while the leading edge of the severed web can be glued to a new core inserted in the winder between the drums (12,14).

Title: Wood splitter
Inventor: JANCZAK JERZY
IPC: B27L/
Filed: 1991-12-27
Abstract: A wood splitter comprises a fixedly mounted splitting wedge (2) and a pressure plate (4) which is driven by means of hydraulic devices (5, 6) so as to feed pieces of wood (3) onto the splitting wedge.

Inventor: BALIT ROBERT
IPC: B32B33/00
Filed: 1993-10-08
Abstract: The stretchable and water resistant laminated fabric composition comprises two layers of stretchable fabrics bonded together by a heat activated adhesive comprising a urethane polymer suspended in a toluene containing solvent, in a proportion of about 40 % by weight of urethane polymer. Such an adhesive leaves stretchability properties of the fabrics of the layers substantially intact and provides a water resistant bond between said layers. The process for making the laminated fabric composition comprises the steps of: selecting two pieces of fabrics having given stretchability properties; coating at least one of the pieces with the adhesive; lying each coated piece in a ventilated atmosphere until the solvent in the adhesive is substantially evaporated: assembling and pressing both pieces of fabrics together for producing the laminated fabric composition; and lying the assembled laminated fabric composition in a temperate atmosphere for a predetermined period of time until the urethane polymer is substantially polymerized. The process may comprises, after the step of assembling and pressing, the additional steps of: heating the laminated fabric composition at a predetermined heating temperature; and molding the laminated fabric composition for producing a three-dimensional shaping. The fabric composition is particularly useful for making swimsuits.

IPC: H04L29/06
Filed: 1994-07-11
Abstract: The invention prevents unauthorized use of data in communications. When terminals with different data transmission rates are simultaneously connected to a host computer, the host computer sets a single common data communication rate to all the terminals to assure synchronization. The host computer is connected each terminal via communications network. The host computer sends a data body to each terminal over a unilateral communications link in a cyclic manner while a bilateral communications link is established between the host computer and each terminal.      Response to an individual request from each terminal, the host computer downloads descrambling data for descrambling and a loader for executing the data body. The host computer determines from among the terminals, any terminal having a communications means that sets the lowest data transmission rate, and sets the data transmission rates of the terminals simultaneously connected thereto to the lowest rate.
